DAVID N. COLLUM, OF BLOOMINGTON, ILLINOIS.

GORN-IELANTER.

Application filed October 12, 1916.

To all whom it may concern:

Be it known that I, DAVID N. CoLLUM, citizen of the United States, residing at Bloomington, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Corn-Planters, of which the following is a specification.

My invention relates to a new and useful improvement in corn planters. It provides a device which is a wireless planter, adapted for check row planting. The novel features of my device comprise means for dropping the corn at certain predetermined intervals and means for marking both the distinct guiding line for the direc tion of the planter and also the hill marks where the corn is to be dropped. These two means are operated in my device by the same mechanism in such a. way that the two operations are synchronized, thus insuring regular alinement of the check rows. My device also includes means for so adjusting the planting and marking means, as to regulate the occurrence of the operation of thesemeans to correct any variations in location, which may have resulted in the travel of the corn planter.

The invention consists in the details of construction hereinafter pointed out.

In the annexed drawings: I

This movement of the rod 86 causes the not lied portion 72 to pass under the latch 65 and permits the lip 73-to contact with the ll) 68, when the latch'tio rests in he notch is theoperatingrod 36 reaches the limit ot' its rearward inoveinent through the rod 411 parts [not shown] operate in an well know in open the teed dot s and. dro n for planting The gasses oti of the finger 98.. contacts elevated moves the i the tappet portions 31 and 39 causes the tappet iii to revolve, thus restoring the tappet Qand its finger to norina osition; which increinent throngh'the toothed portions 80 and 3 lcauses the segmental plate" 33 to more forward and through the studs one segi'nental cross-arnr20 carries the finger 21 forward thus moving the operating rod 36 forwardly. This forward movement of the rod through the contacting clips '73 and 68 carries with the rod thronghthelatch rel a the marker rod 75 and its marker head ('9 which are rotatedlo the pi :lllG of the contact of the 'CllSk with the l ground. The rotation of the marker head 79' carries the projection 83 out of the substantially perpendicular position to the substantially horizontal position and the rod 81 from the substantially horizontal position to the substantially perpendicular position, thus raising the disk 85 from contactwith the ground and bringing the knife edge 89' into momentary contact with the ground, which contact causes the marker further to revolve, thus reversing the relative positions of the rod 81 and the projection 82 and carrying the knife edge 89 out of contact with the ground and the disk 8% into contact with the ground. N hen these operations have been completed, the second projection '77 has reached the position formerly occupied by the first projec tion 77 and before the completion of these operations the forward movement of the latch has been sufficient to lift the latch through inter-action of the weighted portion 69, its beveled face 71 and the yoke T0, so that the lip 68 is disengaged from the lip 73 and the, springs 61, 61, return the rods 61, 57 and 58 to their normal positions, thus extending the projections 60 from without the apertures 59, so that the projection 77 contacts with the projection 60. The change of parts accomplished in the revolution through 180 degrees of the marker head 79 results in the breaking of the guide mark made by the periphery 87 [indicated by C in Fig. 6], the distinct hill niarkamade by the momentary contact of the knife edge 89 [indicated by B in Fig. 6] and the guide mark made by the periphery 86 [indicated by A in Fig. 6].

The forward movement of the rod 36, through the rod etl, rock arm 42, rock shaft i3, collars 4.7, jaws d8, pins 49, slides 50, dogs 51 and ratchet-plates 52, supplies a new charge of corn, through the chutes 5i and the shoes 55 to the planting doors 56. The spring 45, through the hook 14, assists the operation of the rock shaft and its con necting parts.

The stay-rod 9i serves to brace the marker rod '75 in operative position and is adapted to move from one side of the planter to the other on the guide frame 96 as the marker rod is extended first on one side and then on the other. This change in the position of the marker rod is made possible by the use of the loop 7d and the duplication of the projections 60 to serve alternatively on each side. The universal joint 78 is provided in the marker rod 75 in order to take care of any inequalities in the ground over which the marker head 79 passes.

It is apparent from the foregoing description of the operation of the device that the process of the planting the hills and making the hill marks is automatically regulated by the travel of the pins 14 controlled by the traction wheel 12, which measure the distance between the hills. As it frequently happens that inequalities in the ground overwhich the planter travels at which the planting and marking should e done before the device is in position to operate, he may accelerate the operation by moving the adjusting lever 15 rearwardly, thus reducing the distance through which the pin 14 must travel to actuate the mechanism.

It will be seen, therefore, that by the use of this adjusting lever 15 the time of the operation of the planting and marking means may be controlled by the operator so as to insure proper check rowing.

1. The combination in a corn planter of means for dropping corn; means for markthe line of travel of the corn planter; means for marking the place where corn is to be dropped; a single means for controlling the operation of the dropping means and the place marking means; and means constantly adjustable during the operation of the controlling means for adjusting the controlling means to vary the time of operation of the dropping means and the place marking means.
